Alfresco unvailable after create dinamic content model

[vicsaego]

I have create a content model by uploading a file to /Company Home/Data Dictionary/Models. After activated my Alfresco system has become unvailable. The problem likewise is the content model definition file. My question is : How to deactivate o remove this new content model dinamically activate. (Activate checkbox in Vew Details).
I cannot remove de file because is dinamyc and is not stored in {alfresco_directory_installation}/tomcat/share/alfresco/extension.

Thanks very much in advance
